Inside Line is reporting today that the Model S Signature Performance, the top-of-the-line trim level, is already sold out and Tesla Motors is no longer accepting pre-orders. Customers now wanting to purchase the Model S Signature Performance will have to be put on a waiting list.

The Signature Performance ups the ante with an 85 kWh lithium-ion battery pack (8-year, unlimited miles warranty). As its name implies, performance improves greatly with 0-60 times dropping to 4.4 seconds while the top speed increases to 130 mph. The maximum driving range of the Signature Performance is listed at 300 miles.

The first deliveries of the Model S Signature Performance will begin on June 22. Those who have ponied up for the standard Model S will receive their vehicles later this fall. Those who haven't already pre-ordered the standard Model S still have time to get in line; Tesla is still accepting $5,000 deposits for the vehicle.
